Torrential rain before noon wreaked havoc in Himachal today as two main roads linking Chowari sub-divisional headquarters with Chamba, the neighbouring Nurpur subdivision in Kangra and Pathankot in Punjab were severed. On the 5-kilometre Lahru-Chowari link road, a 100-metre stretch was badly damaged. Similarly, the Chowari-Chamba road via Jot has also snapped due to damage near Kut in Chowari.
